PHOENIX (CBS/AP) -- Phillies starting pitcher Taijuan Walker put on a strikeout show Tuesday night in Mexico's 2-1 win over Great Britain in the World Baseball Classic.

Walker struck out eight batters in four scoreless innings to help Mexico improve to 2-1 in Group C. Britain fell to 1-3.

Alexis Wilson had the go-ahead single in the seventh inning that helped Mexico edge Britain.

St. Louis Cardinals relief pitcher Giovanny Gallegos worked the ninth to earn the save.

Britain tied it 1-all in the sixth on B.J. Murray Jr.'s run-scoring single. Right-handed Tahnaj Thomas took the loss after giving up Wilson's single in the seventh.

The final day of Group C play on Wednesday will feature two important games.

The winner of Canada-Mexico advances to the quarterfinals, while the United States can also advance if it beats Colombia.
